14-Channel Programmable Switchable I
TFT-LCD Reference Voltage Generator
with Integrated 4-Channel Static Gamma
Drivers
The ISL24006 is a 14-channel programmable switchable
reference voltage generator with four channels of static
gamma drivers integrated, for a complete 18-channel total
gamma solution for TFT-LCD displays. The 14-channel
programmable switchable configuration allows switching
between two gamma curves.
The ISL24006 is divided into two banks of seven generators:
one designed to cover the range from V
the remaining seven channels covering the range from
V
and low reference inputs, with integrated buffers (four static
gamma drivers) to drive the column driver internal DAC
resistor string to within 0.2V from the top and bottom rails.
An output MUX is used to switch between the two curves in
less than 1µs. Switching is controlled using an external
select pin.
ISL24006 includes an I
offset values.
ISL24006 is available in the 38-pin QFN package and is
specified for operation over the -40°C to +85°C temperature
range.
Ordering Information
NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
